When PS4 firmware 4.05 was released, I speculated it was a reply from Sony to the recent announce of a PS4 jailbreak on firmware 4.01. The authors of the jailbreak, Chaitin tech,  had announced they would disclose the exploit to Sony. People have been fast to let me know that patching a vulnerability so quickly after the announce was unlikely (unless the chaitin hackers had disclosed the issue to Sony a while ago).

Today, PS4 firmware 4.06 was just released, and a few familiar names of the PS3/PS4 hacking scene have come out of the woods to pretty much confirm that this patches, if not all, at least some of the exploits that were used by several groups working on PS4 hacks.

Flat_z, for example, stated: “Thanks to the Chinese guys, 4.06 fixed it :/”.

There is no guarantee at this point that anyone plans to release anything for PS4 4.01 or 4.05. The tweets above are only some data points that seem to confirm the vulnerability exists in firmware 4.05 as well, has been patched with PS4 4.06, and that more groups than just Chaitin tech knew about the vulnerability.

It goes without saying that if you have any expectation to hack your PS4 one day, now’s the time to not update to firmware 4.06. Personally, my plan is to stay on 4.01 with my current console, and buy a PS4 slim as my main gaming rig moving forward.

Sony’s official description of firmware 4.06 is your typical performance/stability improvement statement:

This system software update improves the quality of the system performance.
